Thanks Grannynannywanny, after about an hour of transferring my phone contents over and 'porting' my number I've managed to reset the new one to factory settings, it's going back on Wednesday, I've got to wait for DPD as it's a lithium battery.
I really thought I'd cracked it, I checked O2 did it, and the phone could use it, Tesco should offer the service as they are piggy backing on 02. Every little hasn't helped this time!
Someone needs to go back to Junior School himself.
Things that (sometimes unreasonably) get on your nerves...hopefully lighthearted




Hope you can soon breath a sigh of relief and say "finally"
